LASTING-MACHINE.

Specification of Letters Patent.

Patented Apr. 1, 1913.

Application filed August 8, 1910. Serial No. 576,038.

To ad Awim/n, 'it may concern Be it known that I, ERAs'rUs E. IVINKLEY,a citizen of the United States, residing at Lynn, in the county of Essexand State of Massachusetts, have invented certain new and usefulImprovements in Lasting-Machines; and I do hereby declare the followingto be a full, clear, and exact description of the invention, such aswill enable others skilled in the art to which it appertains to make anduse the same.

The presentinvention relates to certain new and useful improvements inlasting machines and more particularly to that type of .lasting machinescommonly known as the hand method lasting machine.

It is desirable in lasting the better grade of shoes and in last-ingshoes in which the pulling over operation has been ineiiicientlyperformed, for the operator, in order to properly last the shank, toperform this step 1n the operation by hand. A spindle is commonlyprovided upon the bench at one side of the machine and prior to lastingone side of the shoe the operator will spindle the last, seize themargin of the upper with hand lasting pincers, at a point about oppositethe ball of the last, and will then draw on the upper with a slow steadypull in a direction toward the heel and across t-he instep, such a pullbeing necessary to properl draw the upper at' the instep to the woo Theupper at this point is generally slack and stands out from the body ofthe last owing to the sharp inward curvature of the last at the shankand a sharp quick pull which is suliicientto properly draw over theupper at the ball of the last, would not effectually draw over the upperat this point. After having thus stretched the upper and drawn it to thewood it is held tightly in place by the operator until the first tackhas been driven by the machine at about the ball of the last. After oneside of the shoe has been lasted, the last is again spindled, the marginof the upper at the opposite side of the ball of the shoe is seized byhand piucers at the instep and the upper is drawn to the .wood bystretching it over that side of the last. A tack is driven at this pointand the remainder of the upper upon this side of the shoe is then lastedas before.

The principal object of the present invention is to enable the upper tobe evenly and tightly drawn to the body of the last at the shank portionby mechanical means.

Vith this end in view 011e feature of the invention comprises mechanismfor giving a slow upward and overdiaw movement to the plncers after theupper has been grasped at the shank portion.

A further object of the invention is to provide means which will enablethe pincers of the lasting machine to properly grasp the margin of theupper and draw the upper over at the shank portion of the last whenoperating upon shoes in which the ed e of the upper at the shank of theshoe elther does not extend upwardly to the level of the bottom of thelast or in which the upper stands out from t-he body of the lastat theshank portion.

With this object in View a further feature of the invention contemplatesthe provision of a movable bottom rest for the last with mechanism forautomatically moving the bottom rest when the shank portion of the upperis to be drawn over into a position where the upper of the shoe may begrasped by the pincers at a point farther removed from the sole than ispossible when operating upon other portions of the shoe.

Still further features of the invention will be more fully described inthe accompanying pacification and defined in the appended aims.

In the accompanying drawings illustrating the preferred form of theinvention, Figure 1 represents a side elevation of a lastin machine withthe present invention ap lie thereto; Fig. 2 represents a right-hanelevation of the machine shown in Fig. 1, with the upper portion of thedriving pulley broken away, and illustrating the mechanism for movingthe work support and for securing a slow movement of the pincers; Fig. 3is a detail of the operating mechanism for the work support; Fig. 4 is asection upon the line 4 4 of Fig. 3; Fig. 5 is an end elevation of thework support shown in Fig. 3; Fig. 6 is a longitudinal section throughthe main driving pulley and shaft illustrating the mechanism forsecuring a slow movement of the pincers; Fig. 7 is a section upon theline 7-7 of Fig. 6; Fig. 8 is a sectional View taken from the line 8--8of Fig. 6 and showing a detail of the clutch which is employed; and Fig.9 is a detail showing the cage or retaining ring employed for holdingthe rolls of the clutch in place.

The resent invention is preferably illustrated 1n connection with amachine of the type shown and described in United States Letters Patentto S. W. Ladd, No. 597,821, dated January 11, 1898, but it is to beunderstood that the device which is thc subject of the present inventionis capable of general application upon various types of hand methodlasting machine, and it is not to be considered as limited in its use tothe particular type of lasting machine shown in the drawings. The shoeis operated upon in this type of machine by holding the last bottomupward against the bottom rest l. The margin of the upper of the shoe isthen grasped by a pair of movable pincers 3, which, after securing afirm hold on the upper, are moved first upward and then inward towardthe center lino of the sole to draw it uniformly and evenly to the bodyof the last. The upper is then held in this position of the pincerswhile the tacker mechanism 4 drives a tack through the upper and securesit in position at this point, the tack being held by a tack block 2.This mode of operation is Old and well known in the art, as may be seenfrom an inspection of the patent to S. W. Ladd hereinbefore referred to,and forms no part of the present invention. In all previous hand methodlasting machines, however, in order that the upper may be properly drawnto the wood across the instep, it has been necessary, when lasting theshank of a shoe, to spindle the last and to perform this portion of theoperation with care by hand. This is due to the fact that th-epincers,in order to properly draw the upper to the body of the last at thestart, must have a slower relative overdrawing movement than is providedby the ordinary pincer operating mechanism or than is needed in lastingthe upper at the forepart of the shoe.

In the present machine mechanism is pro vided for giving a relativelyslow movement to the pincers when drawing over the upper of the shoe atthe shank, as it is found that this slow movement draws the upper to thewood more tightly and evenly than would be possible with the quickmovement of the pincers which is employed in drawing over the forepartof the shoe.

In some cases when the shoe comes to the lasting machine the upper isslack at the shank and therefore the margin of the upper does notproject beyond the plane of the sole as it should. In other cases, theupper stands out from the body of the last at the shank owing toimproper pulling over and other causes well known to those skilled inthe art. In either of these or similar cases when the shoe comes fromthe puller-over with the upper improperly positioned at the shank, it isnecessary to provide the machine with some auxiliary means which willenable the pincers to properly seize the mar` gin of the upper at thispoint as the pincers ordinarily would not have the requisite movementnecessary to reach the upper if the shoe were held in its normalposition. In order to overcome this difficulty an auxiliary mechanismhas been provided for moving the usual bottom rest upward to enable theshoe to be raised to a position where the margin of the upper may beseized properly by the pincers. The mechanism for moving the bottom restoperates preferably in conjunction with the mechanism for giving a slowmove-nient to the pincers but these mechanisms may be disconnected andallow the bottom rest to be held continuously in a stationary positionwhen so desired.

It is not desired, of course, to affect the normal speed and operationof the lasting machine during the lasting of the ball and toe of theshoe, and to this end of the mechanism for securing aslow movement ofthe pincers and operating the bottom rest is conveniently thrown intooperation by a hand lever 5 which is attached to one end of a rock shaft6 mounted in brackets 7 upon the frame of the machine. The rock shaft. 6upon being oscillated slides the cam roll 8 and arm 9 mounted upon theshaft 10 longitudinally in the supporting bracket ll. The cam roll 8engages with a plate cam 12, but it will be noted that the cam 12comprises an outer circular surface 13 and an inner cam path 14. The camroll, in the normal operation of the machine, ordinarily travels incontact with the outer' surface 13 and no movement downward is impartedthereto, but upon movement of the hand lever 5 by the operator the camroll 8 is moved inwardly and engages with the cam path 14. The mechanismby which motion is transmitted fro-1n the rock shaft 6 to the shaft 10to move the same longitudinally conveniently comprises an arm 16 sleevedto the outer end of the rock shaft and locked against rotationrelatively thereto, and a forked lever 17 pivotally connected to thefree end of the arm 16 and having its forked end embracing the shaft 10and bearing against the hub of the arm 9. In order that a verticalmovement of the forked lever 17 shall move the arm 9 and shaft 10longitudinally, the lever 17 is provided with wedge-shaped surfaces 18,shown in Fig. 1, upon the face of the lever contacting with the arm 9.

The preferred form of t-he path cam is one similar to that illustrated,in which the cam produces an initial movement of the various mechanismsby engagement of the cam roll with the inclined port-ion 21 of the campath, the cam path being next provided with a dwell 2O during which theparts are held in the position to which they have initially moved, thecam roll being then returned to its original position by the portion 1S)of the cam path, restoring the mechanisms to their normal position. Themovement of the cam roll by the cam accomplishes two distinct results.Upon engagement of the cam roll 8 with the portion 21 of the cam path,the bottom rest 1 is moved upwardly and over a certain predeterminedamount, and at the same time the driving mechanism for moving thepincers is automatically regulated to secure a slow movement of thepincers. lVliile the cam roll S travels through the portion 20 of thecam path, the bottom rest 1 is held in its raised position and thepineers 3, having grasped the upper, are retracted with a slow movement.Simultaneously with the pincers reaching the limit of their upwardmovement the cam roll engages with the portion 19 of the cam path, andthe bottom rest 1 is moved down and back to its normal position,securing a further drawing over of the upper of the shoe, at the sametime the slow speed is automaticallyT thrown out.

It is considered desirable to automatically return the cam roll 8 to itsnormal position in contact with the surface 13 of the cam 12, and tothis end a project-ion 12 is formed upon the edge of the. cam 12contacting with arm 9 and moving it outwardly upon engagement therewith.lVith this arrangement the mechanism for securing a` slow movement ofthe pincers will only be operative during one revolution of the drivingshaft 54 unless the operator again moves the hand lever 5. It will beunderstood that the wedge 18 has been lowered before the completion ofthis revolution, as the weight of the parts at the other side of theshaft 6, from the handle 5, is sufficient to cause the wedge to drop onthe release of the handle by the operator. The bottom rest l is slidablymount-ed for longitudinal movement in a box 22 and is provided upon itsupper face with a toothed rack 23 which engages with an oscillatorytoothed segment 24. The bottom rest 1 and supporting box 22 are mountedupon a cross-head 25, which slides in vertical ways 26 in the fra-me. Avertical movement is given to the crosshead 25 b v engagement of anoscillatory toothed segment 27 with a toothed rack 28 formed upon aprojecting face of the crosshead. The frame is slotted at 28*l and .therack projects therethrough to prevent twisting movement of thecross-head. The segment.- 27 is fixedly mounted upon a rock shaft 29which is mounted in brackets 30 secured to the frame of the machine. The

rock shaft. 29 is operated upon movement of the cam roll S through atrain of mechanism comprising an arm 31 fixed upon the outer end of therock shaft 29 and having a link 32 pivotally connected to its free end.The link 32 is pivotally connected at its lower end to a slotted segment33 which is fixed upon one end of a shaft 34. In order that theoscillatory movement of the shaft 29 may be varied, and, if so desired,may be entirely discontinued, the curved segment 1s attached to theshaft 34 b v means of a yoke 35, and the link 32 is adjustably securedto the segment 33 by a bolt' and nut 36. The yoke connection enables thclower portion of the link 32 to be secured 1n the segment at. a pointcoincident with the axis about which the segment 33 oscillates, so that,when so secured, upon oscillation of the segmentno resultant movementwill be communicated to the link 32 and rock shaft 29. The value of thisfeature will be appreciated when it is considered that 1n operating uponman v kinds of shoes it is only desired to secure the slow movement ofthe pincers and not the additional movement of the bottom rest which canbe easily retained in locked position and hold the last stationary whilethe upper is being operated upon by the pincers. The rock shaft 34 isoscillated upon movement of the arm 9 through a system of linkagescomprising an arm 37 mounted upon the hub of the arm 9 and movabletherewith. The arm 37 has a link 38 connected to its free end and thelink 3S is connected through a universal joint- 39 and a short rod 40with the pivotal point 41 of a toggle. The arm 42 of the toggle isformed integrally with a sleeve 43 which is loosely supported upon theshaft 6. The sleeve 43 has an arm 44 fixed thereto and extending fromthe side opposite the arm 42. The arm 44 oscillates the shaft 34 througha link 45 connected to its free end and the arm 46 which is fixed to theshaft 34. The opposite arm 47 of the toggle is connected at its free end,to a lever 48 pivoted at its central point on the frame of the machineand engagin at its upper end the head of a bolt 49 whic i is normallyheld inward by a coiled spring 50 bearing against a nut 51 at one endand bearing at its opposite end against a projecting lug 52 formed uponthe band 53 of a friction brake mounted upon the main driving shaft 54of the machine. A movement of the cam roll 8 and arm`9 will thus operatethrough the toggle to oscillate the shaft. 29 and move the bottom rest 1upwardly, and will at the same time rock the lever 48 about its pivotalpoint, moving the upper end outwardly, compressing the spring 50 totighten the brake band 53 and apply the friction brake. The movement ofthe rest 1 due to the oseillation of the shaft 29 will continue in avertical direction until the free end 55 of an arm 56 contacts with theupper wall of the recess 57 into which the arm 56 projects. When the endof the arm 56 is stopped from further movement in a vertical direction,the continued upward movement of the cross-head 25 will result inoscillating the toothed segment Q4 which is fixed to the arm 5G andpivotally mounted at 5S in the crosshead 25.

The oscillation of the segment 24 will withdraw the rest 1 in the box 22against the action of the spring 59 which is fastened atl one end to thebox and at the other end to a portion of the rest 1. Upon theoscillation of the shaft 29 in the reverse direction the spring 39 willretain the free end of the arm 5G against the upper wall of the recess57 until the rest has been forced out of the box QQ to its normalposition when the movement of the rest will be vertically downward. Asit is necessary for the bottom rest to be returned to its original ornormal position in order that the tack may be properly driven, a pin GOis mounted in the frame of the machine extending into the recess 57 andpositioned to Contact with the lower edge of the arm 56 in order thatthe rest 1 shall be positively forced over into its proper positionbefore the tack is driven into the last. It will now be seen that inaddition to the upward and over-draw movement of the pincers, there isalso the movement of the bottom rest back to its normal position, whichis the reverse of the upward movement of the pincers, so that the resultis an increased drawing over of the upper at this point. The pincers areyieldably mounted so that when the strain upon the upper due to thedownward movementof the bottom rest exceeds a certain amount the pincerswill yield and not tear the upper. In order that the rest shall belocked and held rigidly in place during the tack-driving operation, aspring-pressed pin G1 is provided, the end of which projects into a holein the side face of the rest 1 when in its norlnal position. The pin 6lis mounted in a slot in the frame of the machine, and is normally forcedinward by a coiled spring G2. In order that the botto-m rest may bereleased upon its upward movement, a vertical forked finger 63 is boltedto the side of the cross-head slide 64, and has a wedge-shaped lower endG5 engaging with the head of the pin G1, so that upon upward movement ofthe rest 1, the wedge G5 engaging with the head of the pin 61 will forcethe pin outwardly and release the wor i support, allowing it to bewithdrawn.

The slow movement of the pincers 8 is secured upon tightening the brakeband 53, and it will be seen that this is coincident with the upwardmovement of the rest 1 and that the slow movement will continue during`the time that the rest is maintained in its raised position. Undernormal conditions the drive shaft 54 will be driven directly from thedrive pulley 66 when the brake band 53 is loose. A sleeve 67 is keyed tothe shaft 54 and has a gear 68 formed integrally upon one end thereof. Asecond sleeve 69 is mounted loosely upon the sleeve 67 and has a gear 70fastened thereto. The gears G8 and 70 mesh respectively with gears 71and 72, keyed together and rotatably mounted upon a radial arm of thedrive pulley G6. rThe gears 71 and 72 have a different number of teethand will tend to drivethe gears GS and 70 respectively at differentspeeds. The sleeve (59 has a series of radial projecting arms 73 uponthe outer ends of which is fastened the gear '70. These arms 73 of thesleeve (S9 form a portion of what is commonly known as a Horton clutch`and a cage or retaining ring 74 is loosely supported upon the sleeve (S9and provided with a series of longitudinally projecting arms whichproject between the arms 73 of the sleeve 69. rThe portions of thesleeve G9 between the arms '73 and projecting beyond the same areslightly iiattened, as shown clearly in Figs. 7 and S. The arms 75 ofthe retaining ring 74 are provided with recesses 7G, in which are heldballs or rolls 77. As thel driving pulleys GG and gears 71 and 72 arerevolved, thegears (58 and 70 will tend to revolve atdifferent speeds,the gear 70 rotating faster than the gear G8, and as the brake band isnormally loose, the retaining ring 74 will be allowed to rotate freelyand the arms 75 of the retaining ringl 74 will be moved by the radialarms 73 relatively to the gear (38. wedging the balls 77 between thesurface of the sleeve 69 and the inner flanged portion 7S of the gear G8locking the two gears G8 and 70 against rotation relatively to (ineanother. It is preferred. in order to secure a. more positive action ofthe clutch, to employ two sets of springs SO-Sl which bear against thearm 75 of the ring 74 and the balls 77 respectively, and tend tonormally lock the clutch. Owing to the fact that the gears 71 and 72will tend to rotate the gears GS and 70 at different speeds, t-he shaft54 will be driven directly from the pulley 6G as soon as the gears G8and 70 are locked to one another, in the same manner as if the pulley 66were keyed directly to the shaft 54. l-Vhen the brake band is tightened,however, the retaining ring 74 and the gear 7() will be held againstrotation and will prevent the balls 77 of the clutch from becoming`wedged into place and locking the gears 68 and 70 together. Then, as thegear 70 is held stationary, a slow rotatio-n will be imparted to thegear 68 to rotate the shaft 54 which is the result of the differentialmovement between the gears 71 and 72. In order that the gears may beproperly inelosed from dust, and the operator protected from injury bythe gearing, a shield 79 is fastened to the drive pulley and covers thevarious gears.
